         NOW, THEREFORE, KNOW ALL MEN BY THESE PRESENTS, that for and in
consideration of the terms, conditions and agreements contained herein and for
other good and valuable consideration, the receipt and sufficiency of which is
hereby acknowledged, Lender, Borrower and the Guarantors agree as follows:

         1. INCREASE IN AVAILABLE COMMITMENT. From and after the effective date
hereof, the maximum amount of the revolving credit facility under the Credit
Agreement shall be increased from $15,000,000.00, to $25,000,000.00.
Accordingly, the definition of "AVAILABLE COMMITMENT" set forth in Section 1.1
of the Credit Agreement shall be amended to read in its entirety as follows:
